SAFETY-RAZOR.

Specification of Letters Patent.

To all fwwm t may concern.'

Be it known that I, HARRY W. GRnnN- BRmR, a citizen of the United States, res1d ing at 251 New York avenue, Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Safety-Razors, of which the following, taken in connection with the accompanying sheet of drawings, is a full, clear, and concise description.

This invention relates to safety razors of the detachable type and has for one of its objects a provision of this type of razor characterized by simplicity of construction and ease of assembly and adjustment of parts.

Another object is the production of a safety razor in which can be used a blade of thin or sheet metal having a single cutting edge, the blade being so held as to permit the changing of the angle of its cutting e e.

ther objects of the invention have to do with certain features of construction and arrangements which are hereinafter set forth and which have to do more particularly with the parts which compose the blade clamping and handle portions of the razor. y

The invention is illustrated in the accompanying drawings in which,

Figures 1, 2 and 3 are front, side and rear elevation views, respectively, of a razor embodying my improvements as preferably constructed.

Fig. 4 is a section taken on line 4-4 of Fig. 1.

Fig. 5 shows the several elements of the razor disassembled.

The razor shown in the drawings is comprised in general of a head 1 and a detachable handle 2. The head portion includes a blade support 3, a clamping member 4 and a blade 5 which is held between its support and the clamping member. The blade support 3 is provided with a guard 6 on one of its longitudinal edges and a pair of spaced apart lugs 16 on the opposite edge, the latter functloning to aline or position the blade 5 in any endwise direction. An abutment 7 is formed centrally on the under surface of the blade support 3 and this abutment is provided wlth a threaded recess which serves as a socket for receiving the external screw threads formed on the upper end of the handle 2, Slnce the support 3 is preferably Patented Jan. 22, 1918.

serian No. 169,182.

a composition, the abutment 7 is formed integral with the body portion thereof, having the adjacent metal on the front or contacting surface of the support either recessed or cast out for a purpose hereinafter more fully described.

The clamping member 4 is preferably of one piece and comprises a blade engaging portion 8 with a depending portion 9 bent at an acute angle to the portion 8 and extending downwardly a sufiicient distance so that a second offset portion 10 will lie in a plane substantially perpendicular to the handle 2 and not intersect with the lower edge of the blade support 3. The offset portion 10 terminates 1n a Ipair of oppositely disposed and upwardly directed arms 1l. The portion 10 of the clamping member is provided with an elongated slot or aperture 12 which permits the passage therethrough ofthe upper end of the handle 2 when inserted into the socket formed in the abutment 7. Lips or turned-over edges 13 function as a stop for limiting the rearward movement of the blade support 3 whenl the razor is assembled. The relation of the contacting parts of the blade support 3 and clamping member 4 is such that the arms 11 impinge against the under surface of the support and rmly hold these two parts together by means of friction. The lips 13 have the effect of constituting a hinge or ivot when the support and clamping memer is sprung apart to insert the blade 5. It may be mentioned that there is a certain degree of resiliency to the various portions .comprising the clamping member 4 and this feature is relied upon when inserting the blade.

The handle 2 is cylindrical in shape, being reduced at its upper end and having a hollow core. External and internal threads are formed upon the reduced end of the handle 2. A shank 14 is adapted to be received within the handle and has an enlarged portion formed upon one end, while the major portion of its length is considerably reduced 1n diameter and is provided with threads adjacent the end thereof. The reduced end of the shank 14 when screwed upwardly is adapted to project beyond the end of the handle 2 so as to contact with the blade 5. Since. the normal position of the blade is to lie in close engagement with the guard, by rotating the shank `14 the upper end thereof shank 14 so that the upper yend thereof does not extend beyond the corresponding end of the handle 2, then holding the razor by the handle and applying pressure with the thumb against the portion 9 of the clamping` member 4,l the outer edge of the portion 8 may be tilted upwardly so as to afford a space between the support 3 and the adjacent part of the clamping member 4. After the blade has been inserted between the clamping member 4 and the support 3 it is easily of the ears l5 thereofpositioned by means I coming in contact with lugs 16. The angle .of the cutting edge of the blade may then bey adjusted as previously described. As a matter of convenience the body of the handle and theenlarged portion of the shank may be knurled to alst in turning these parts when desired.

While I have herein shown and particularly described the preferred embodiment of my invention I do not wish to be limited to the precise details of construction and arrangement illustrated, as changes may readily be made without departing from the spirit and scope of my invention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States, is:

l. In a safety razor, the combination with a blade of a blade support, a clamping member adapted to frictlonally engage said blade and having a downwardly depending portion terminating in. forked members adapted to abut against said blade support, so as to clamp the blade and blade support therebetween, a handle, there being an aperture made in said depending portion to permit the passage therethrou h of said handle whereby to anchorsaid clamping member to said handle, and means on said blade support for attaching said handle.

2. In a safety razor, the combination of a blade support provided with a ard, a clamping member vadapted to frictionally engage with said support, said clamping member having a downwardly depending portion provided with an offset portion terminating in upwardly directed forked members adapted to abut against said blade support, a handle, there bein an aperture made in said offset portion a apted to permit the passage therethrough of a handle whereby to anchor said clamping member to said handle, and a socket on said blade support for attaching said handle.
